FEATHERING-MACHINE.

Specification of Letters Patent.

Patented Aug. 9, 1910.

Application filed May 13, 1910. Serial No. 561,179.

T 0 all whom it may concern:

Be it known that we, Gnonon J. KILB, a citizen of the United States, anda resident of the city of Covington, in the county of Kenton and Stateof Kentucky, and THEO- BALD RINGENBAOH, a citizen of the United States,and a resident of Springlake, in the county of Kenton and StateofKentucky, have invented certain new and useful Improvements inFeathering-Machines, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawing, forming apart of this specification.

The object of our invention is to provide a construction of featheredging and beveling machines for beveling off the edges of any kind ofleather for soles, harness, saddlery and the like, but more particularlydesigned in our preferred form for feathering the soles of shoes.

Our machine is particularly designed for feathering soles after theupper is secured to the sole, although obviously the machine may also beused for feathering soles and like material before the uppers areattached.

Our invention consists of that certain novel construction andarrangement of parts to be hereinafter particularly pointed out andclaimed whereby the above results are accomplished.

In the drawings, Figure 1 is a side elevation of our improved machine.Fig. 2 is a detail plan view of the knife block. Fig. 3 is a sideelevation of the knife block with part of the knife holding plate brokenaway. Fig. 4 is a front elevation of the knife block and a portion ofthe feed wheel. Fig. 5 is a vertical section through the table lookingtoward the driving gear.

1 is the upper portion of a suitable frame, upon which is mounted thetable 2 for holding the operating parts. Suitably bolted upon this tableis a plate 3 carrying the vertical standards 4, 5, the standard 5 beingprovided with the forward extension 6.

Suitably journaled in the upper end of these standards is a feed wheelshaft 7 which is held in position by the collars 8, 9, secured by setscrews and abutting against the side faces of the standards. The forwardend of this shaft 7 is provided with thefeed .14' to be rotated by thewheel 10 which is secured on the end of the shaft so as to rotatetherewith by a set screw.

Feed wheels of various thicknesses may be employed for difierent kindsof work, and theperipheral surfaces may either be of knurled metal orrubber, or any other suitable material.

The extension 6 from the standard 5 is provided with a depending lug 11grooved out to fit around the outer end of the feed wheel shaft so as tosteady it in its rotation.

Mounted on the opposite end of the feed shaft 7 is the driving gear 12,which is engaged by the pinion 13 journaled on a stud 14 in one of thearms 15 extending laterally from the standard 4. A corresponding arm 16is provided for the standard 4, provided at its outer end with a bearing17 so that the driving pinion 13 can be mounted on either side of themachine to enable the stud shaft driving pulley 18 and belt 19 fromeither side of the machine, as may be most convenient.

20 is the usual loose pulley mounted on the shaft to receive the beltwhen the machine is not running.

21 is a bracket plate position alongside of means of the horizontalextension plate 22 extending rearwardly from the bracket and securelybolted to the under surface of the table. This bracket plate 21 isprovided with two forwardly extending arms 23, 24, suitably apertured atthe outer ends to receive and hold loosely a rod or shaft 25, upon theupper end of which rod is mounted a knife block table plate 26, and inorder to guide and hold the knife block plate in position, its rear end27, as shown in dotted lines in Fig. 1, is guided in a suitable guidewaybetween projecting sides 28 of the bracket. The forward edge of thisknife block plate 26, as viewed from the top, is provided with aninclined edge 29, as shown in Fig. 2, and the thickness of the plate 26at its forward end is beveled off as shown at 80 in Fig. 1. Mounted onthe knife block plate is a guide plate 31 secured to the block by ascrew 32 provided with an enlarged head and with the shank passingthrough thehead 33 in the guide plate.and screwsecured in vertical thestandard 5 by threaded in the top face of'the knife block. The frontedge of this guide plate is pro vided with an inclined edge 34 tocorrespond with the edge 29 of the knife block plate, and the guideplate carries inserted in lateral grooves in the plate the two guiderolls 35 and 36. is a knife holding plate which is secured by screws 37,38 to the side edge of the knife block 26, the screws being insertedthrough slots 39 in the knife holder to allow for adjustment. This knifeholder is L- shaped in cross section, and the upper portion extends overthe upper edge of the knife block so as to leave between the overhangingportion of the knife holder and the knife block a longitudinal recess41, and in this recess the skiving knives 42,43 are located and held inposition with their cutting ends 44, extending over the outer edge ofthe knife block. One knife for cutting a bevel or feather on one sidealone, or two knives for cutting on both sides of a strip of leather maybe used, and this knife, or, these knives are held in position by theheadless set screws 46, 46, for the overhanging portion ofthe knifeholder, and by the headless set screws 47, 47, for the knife block, thetwo sets of set screws bearing in opposite directions and adapted toclamp the knife or knives rigidly in position. The outer end of theknife block underneath the knives is grooved out v at 48.

In order to hold the leather to be trimmed in position when using twoknives for beveling on each side of the leather simultaneously, weprovide a presser foot 49 which is secured by screws 50 through slots inthe upper end of the presser foot plate for ad justment.

The knife block plate is held in position by means of the coilspring 51mounted on the rod 25 and bearing between the bracket arm 23 and thecollar 52 held in adjustable position by the set screw 53. The upwardmovement of the knife block and its supporting rod is limited by thecollar 54 secured by set screw 55 on the rod 25, which bears against theunder surface of the bracket arm 23. The lower end of the rod 25 isprovided with an eye 56, by means of which the rod can be secured bysuitable connection with a foot treadle, not shown, so that bydepressing the foot treadle the rod 25 and the table'block 26 can bedepressed to permit the ready insertion of the leather to be trimmed inposition.

In operating the machine, any kind of a sole, whether with or withoutwelt and whether sewed to the upper or before being sewed can befeathered and both edges trimmed vsimultaneously or only one edge can betrimmed. The edge of. the sole is inserted under the feed roller uponthe edge of the knife-plate table with the side edge of the sole againstthe guide rollers, and the leather is fed against the sharp .edge of theknife or knives and the skiving removed readily and accurately. Theknife table is beveled underneath and the space is entirely clear andunobstructed, so that the fact that the shoe is finished with theoutsole and upper in place is not a detriment, and more satisfactoryresults can be attained as soles when trimmed before the uppers are.secured are apt to get bent and out of shape.

The feed of the material is accomplished by a single feed roller actingfrom above upon the material resting upon a fixed table instead of meansof two feed rollers acting on opposite sides of the material. Thecutting knives can be readily and easily secured and adjusted so as tomake the exact bevel and amount of cut desired, and the knives are heldfirmly and rigidly throughout their length by the several set screwsacting on both sides of the shank of the knife. It isnot necessary toemploy the presser foot when only a single, knife is used, as theleather is readily held in place by the feed roller, but with bothknives the .presser foot is adjusted to bear on the leather as 1t is fedto the knives. To start the ma terial under the feed roller, the knifetable is depressed by the foot treadle so that the roller can press thematerial firmly on the table, andthe distance between the table and thebearing surface of the feed roller can be readily adjusted for thematerial to be treated by adjusting the collars on the supporting knifetable rod. The pressure of the feed roller is directly in line with thecutting edge of the knives so that the leather is held securely inposition as it is fed against the cutter.

Having thusv described our we claim as new and Letters Patent,,is:

1. In a feathering machine, a relatively fixed table and 'a feed rolleracting upon the material to hold and feed it on the table, with anadjustable guide plate secured to the table cooperating with the feedroller to hold the material in proper position, a knife holdercomprising a slotted plate secured to the table, and a knife held undersaid plate with set screws bearing on the shank of the knife to hold theknife rigid and against which the material is fed. f

2. In a feathering machine, a relatively fixed table, with its frontportion cut away toward the rear and beveled underneath, and a feedroller acting from above upon the material to hold and feed it on the.table, and a feathering knife rigidly secured to the table in line withand insidethe feed roller against which the material is fed.

3. In a feathering machine, a relatively fixed table, With its frontportion cut away toward the rear and beveled underneath, and a feedroller acting from above upon the material to hold and feed it on thetable, an adjustable guide plate, With guide rollers secured to thetable in line with the front edge of the table, and a feathering kniferigidly secured to the table in line With and inside the feed rolleragainst which the material is fed.
